Olayemi Cardoso was appointed CBN Governor on 22 September 2023, replacing the Emefiele-era heterodox regime. Key actions: ended Ways-and-Means overdraft financing of the federal government (which had accumulated ~N22 trillion in breach of statutory limits), resumed full MPC meetings on a regular cadence, hiked the monetary policy rate aggressively from 18.75% to 27.5% across 2024 to combat inflation, reintroduced OMO auctions to mop up liquidity, and launched a ten-year bank recapitalisation programme in March 2024 raising minimum capital for international banks to N500bn.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
